RCBS MatchMaster .243 Winchester Neck Bushing Die Set

Description

The RCBS MatchMaster Neck Bushing Die Set is RCBS's top-shelf answer for .243 Winchester handloaders who chase small groups. Instead of working the whole case, the sizing die only touches the neck, leaving the shoulder and body in their fired state. That keeps your brass from stretching and reworking itself every cycle, which is exactly what benchrest and long-range crowds have leaned on bushing dies for over the years. The set pairs a neck sizing die with the MatchMaster micrometer seating die, so you get the full package minus the bushing itself.

What the MatchMaster .243 Neck Sizing Die Does Differently

The heart of this die is the interchangeable neck bushing system. You pick a bushing diameter to set the exact amount of neck tension you want, which is one of the biggest variables in consistent velocity and accuracy. The sizing die also carries a titanium carbo-nitride coated expander that cuts down on brass buildup and makes case extraction smoother on the way out. Worth noting up front: the neck bushings are sold separately, so you'll want to measure a loaded round and order the right size (typically your loaded neck diameter minus about .002 to .003 inch). RCBS bushings fit, and many common brands like Redding will work too.

Seating Bullets With the MatchMaster Die

The seating die is where this set really earns its keep. It uses a bullet loading window, so you drop the bullet in through the side and run the press instead of balancing it on the case mouth and risking a tipped or crushed bullet. An internal sleeve catches and guides the bullet into alignment with the case for concentric results. The oversized micrometer head makes seating depth changes quick and easy to read, with each mark representing one thousandth of an inch. Every die runs a standard 7/8-14 thread, is machined from case hardened steel with hand-polished interiors, made in the USA, and backed by RCBS's limited lifetime warranty.
